Well, our heating and air unit finally went kaput. Greg was very knowledgeable, in helping us decide what unit and size was best for our home. We went with a bigger, more efficient unit, and had our duct work redone for better air flow throughout the house. The has made a BIG difference! The A/C isn't running all the time, and rooms that were previously hot/cold have consistent air flow with the rest of the house. I like that, Greg has called a few times since the install to check, and see how the new unit is working, and if we have any questions. Great service from a family-owned business.
